Abstract:
Assara inouei Yamanaka was used as test insect.The bioactivities of chlorfluazuron，tebufenozide and indoxacarb against eggs，larvae and adults of Assara inouei were studied by immersion and residual film method in the laboratory.The results showed that three insecticides had certain inhibiting effect on survival and reproduction of Assara inouei，and the inhibition effect increased with insecticides concentration increasing.Four hundred-diluted times solution of 50 g?L-1 chlorfluazuron EC had the strongest inhibition effect on egg.Four hundred-diluted times solution of 50 g?L-1 chlorfluazuron EC and 3 000 diluted times solution of 150 g?L-1 indoxacarb EC had the strongest inhibition effect on survival rate of newly hatched larvae and eclosion rate of live larvae，and four hundreddiluted times solution of 50 g?L-1 chlorfluazuron EC showed the most significant inhibition on pupation rate of live larvae.Four hundred-diluted times solution of 50 g?L-1 chlorfluazuron EC was the strongest inhibiting effect on mature larvae survival rate.Four hundred-diluted times solution of 50 g?L-1 chlorfluazuron EC and 3 000 diluted times solution of 150 g?L-1 indoxacarb EC showed the most significant inhibition to pupation rate and eclosion rate of live larvae,3 000 diluted times solution of 150 g?L-1 indoxacarb EC was the strongest inhibiting effect on adult survival rate and single female fecundity of live adult.Four hundred-diluted times solution of 50 g?L-1 chlorfluazuron EC and 1 000 diluted times solution of 20% tebufenozide SC showed the most significant inhibition to egg hatching rate.
